Clear and concise description of the problem

Requirement 1: Visual Gantt Chart Support

In both project management and novel story structuring, the chronological order of events is crucial. To effectively plan, monitor, and dynamically adjust the sequence of activities or plot points, a visual Gantt chart is indispensable. Such a chart should present tasks or narrative beats along a timeline, clearly indicating start/end dates, dependencies, and progress. Moreover, it should support drag‑and‑drop adjustments directly on the timeline, enabling users to reschedule and fine‑tune the flow with ease.

Requirement 2: Card Box with Drag‑and‑Drop Embedding

Given that all elements within the software are represented as objects, the current method of referencing existing objects is rather limited (e.g., only through menus or search queries). To enhance flexibility and user efficiency, we propose adding a "Card Box" – a dedicated container that stores frequently referenced objects. Users can then drag and drop any object from this box directly into their target workspace, achieving quick association and reuse without the need for repeated searches or context switching. This intuitive interaction greatly streamlines workflow and reduces cognitive overhead.

Suggested solution

Add timeline functionality (inspired by Gantt charts) Introduce a visual timeline view that displays event sequences, durations, and dependencies, and supports drag‑and‑drop adjustments for flexible scheduling.

Add drag‑and‑drop embedding Enable users to directly embed any object into target locations via drag‑and‑drop, streamlining content organization and linking.
